MacDill Air Force Base, Florida (CNN) -- All gates at MacDill Air Force Base in Florida will be open Tuesday after being temporarily closed after a heavily armed man and woman were taken into custody when they tried to enter the facility without authorization, an Air Force spokeswoman said.

They were stopped at a gate at the base that houses the headquarters for U.S. troops in Iraq and Afghanistan early Monday evening after they could not show proper identification, Senior Airman Katherine Holt said. A search of the vehicle after they were detained found military-style uniforms and gear and several "rifle-type" weapons, Holt said.

The two were questioned Monday evening, another Air Force spokeswoman, Elizabeth Gosselin said.

Authorities cordoned off their sport utility vehicle and searched it using a robot, but no explosives were found, Holt said. Video showed base personnel removing weapons, ammunition and military-style clothing from the vehicle, which was later towed away.

The Tampa, Florida, installation houses the headquarters of U.S. Central Command, which runs the U.S. wars in Afghanistan and Iraq, as well as the U.S. Special Operations Command.
